We got an e-mail from a supplier that they are changing up the IP addresses with which they reach out to our server. The problem is that new range is a /18 subnet. When trying to look for an answer I find conflicting answers on if it is possible to use a subnet. Is there a way to change this so that one complete ip range /18 is allowed? I mean creating over 16.000 host= rules isn’t really an option.
Thank you in advance for your help.
Currently the part is build as followed:
